mesoderm  [%PREMIUM_LINK%]     (měz'ə-dûrm')  Pronunciation Key 
The middle of the three primary germ layers of the embryos of vertebrates and other complex animals. In vertebrates, the mesoderm gives rise to the muscles, bones, cartilage, connective tissue, blood, blood and lymph vessels, dermis, kidneys, and gonads. The mesoderm develops during gastrulation from either the ectoderm or the endoderm. The embryos of simpler animals lack a mesoderm. Compare ectoderm, endoderm.
